Blind Battle

[SossMan]

2nd round of a Lucky Chances monday tourney ($45 w/ 1 $40 rebuy...I rebuy right away and start w/ t2500)

I start the hand w/ about 3k. I was standing in line to sign up for the tourney and struck up a conversation with the guy who happened to be my opponent on the following hand. He normally plays limit tourneys, and I have a feeling that he plays pretty ABC, maybe a little passive preflop (he raised a limper w/ KK, got a caller in between, was reraised, and flat called preflop, moved in when the flop came K high). That's really the only full hand read I had on him, but he felt pretty straight forward to me (this probably doesn't make sense to you PokerStars folks [img]/images/graemlins/tongue.gif[/img])

Here's the hand:

Blinds 25/50
I have about t3000.
He doubled up in his KK hand and has about t2200 (and a rebuy chip)
Everyone folds to my buddy in the SB, he completes.
I throw in another t100 chip with A [img]/images/graemlins/club.gif[/img]9 [img]/images/graemlins/diamond.gif[/img], he calls.

Flop (t300 in the pot):

A [img]/images/graemlins/diamond.gif[/img] T [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/heart.gif[/img]

He checks, I bet out t300.

He mini-raises to t600.

What in the world do I do there?
